Title: Wireless sensor network–based intelligent safety monitoring system for underground non-coal mine
Inventor: YU XIUWU
IPC: E21F17/18
Filed: 2021-02-23
Granted: 2021-04-29
Abstract: The present disclosure provides a wireless sensor network-based intelligent safety monitoring 
system for an underground non-coal mine. The system includes a plurality of wireless sensor 
subnetworks and a plurality of sensors that are disposed in a mine, and a central switch, a data 
processing server, and a comprehensive supervision platform that are disposed on the ground. The 
wireless sensor subnetwork includes a wireless sensor node, a convergence gateway node, a 
reference node, and a mobile node. The reference node can update a corresponding parameter in a 
data packet of the reference node by using a periodic broadcast signal of another adjacent 
reference node. The wireless sensor node is connected to the sensor. The mobile node is disposed 
on a worker or a mobile device in the mine, and is located through calculation, sorting, and 
comparison based on the data packet of the reference node, a recorded identifier (ID) of an 
adjacent mobile node, and information in a database. The present disclosure can collect 
safety-related environment data and location information of workers in the mine in real time, 
thereby effectively improving safety of operations in the mine.

Title: METHOD FOR DETECTING QUATERNARY AMMONIUM SALT-TYPE CATIONIC SURFACTANTS WITH SULFOCALIX[n]ARENES
Inventor: GUO XIA
IPC: G01N21/64
Filed: 2021-05-25
Granted: 2021-07-22
Abstract: The present disclosure provides a method for detecting quaternary ammonium 
salt-type cationic surfactants with sulfocalix[n]arenes. Fluorescence will be generated 
after sulfocalix[n]arenes bind with the opposite charged quaternary ammonium 
salt-type cationic surfactants to form superamphiphilic molecules, and the higher the 
concentration of the quaternary ammonium salt-type cationic surfactants, the higher the 
fluorescence intensity. The concentration of the quaternary ammonium salt-type 
cationic surfactants in the solution to be tested can be calculated according to the 
relation between the molar ratio of sulfocalix[n]arenes to quaternary ammonium 
salt-type cationic surfactants and the fluorescence intensity. The present disclosure 
employs a simple detection method with a fluorescence spectrophotometer, which can 
effectively identify and detect quaternary ammonium salt-type cationic surfactants by 
using a small amount of sulfocalix[n]arenes; in addition, the detection temperature is 
low, there is no need to conduct the process at high temperature, so it can be applied 
widely.

Title: An estimation method for high outliers in point cloud image processing
Inventor: CHEN FENG
IPC: G06T7/80
Filed: 2021-08-09
Granted: 2021-11-11
Abstract: : 
Robust fitting is a basic technique and has been widely applied in photogrammetry and remote sensing, 
such as geometric correction. As known, typical robust estimators (include M-estimators, S-estimators, 
MM-estimators, etc.) often fail when outlier rate is higher than 50%, even if the outliers are uniformly 
distributed. In this patent, we propose an estimation method for high outliers in point cloud image 
processing, called adaptive M-estimators (AM-estimators). They are still robust under 80% of outliers.  
The proposed AM-estimators are very important supplements of M-estimators. Different from M
estimators, we use a varying parameter (shape-control parameter) instead of the original constant 
parameter in the weight function. The shape-control parameter decreases along with iterations in 
iteratively reweighted least squares, namely, AM-estimators are optimized in a coarse-to-fine manner.  
Extensive synthetic and real experiments show that AM-estimators are superior to M-estimators, S
estimators, MM- estimators, and RANSAC-type methods.

Title: Diffusion Least-Mean Squares Algorithm With time-varying combiner
Inventor: CHEN FENG
IPC: H04W40/02
Filed: 2021-08-09
Granted: 2021-11-11
Abstract: This patent presents an efficient time-varying combination strategy for the 
distributed estimation problem over diffusion networks in order to improve robustness 
against the spatial variation of signal and noise statistics over the network. The main 
content is to design the fusion weight by using the spatial density of node estimation 
parameters in the network. Through simulation experiments, it is proved that the 
fusion weight strategy proposed in this patent can effectively improve the 
performance of distributed least mean square algorithm (DLMS).

Abstract: A ternary composite electrode material for hybrid capacitor and its application. The 
ternary electrode material is NixVyMnzO2, which comprises the following steps: preparing 
nickel acetate-manganese acetate mixed solution and sodium carbonate-ammonia water mixed 
solution, dropwise adding the sodium carbonate-ammonia water mixed solution into the nickel

Abstract: The present invention discloses a reclaiming method for cathode materials of retired 
lithium-ion batteries, which comprises the steps of: putting the cathode material powder of the 
retired lithium-ion battery into a solution filled with supersaturated lithium salt, then, completing 
hydrothermal pressing to compensate lithium, and thus, the first heterogeneous suspension can be 
obtained; after that, filtering and drying the first heterogeneous suspension, and then, mixing the 
obtained reclaimed cathode material seed crystal with the precursor solution and the binder, and 
then, completing ball-milling, and thus, the second heterogeneous suspension can be obtained; after 
that, stirring the second heterogeneous suspensions evenly, then, collecting precursors after 
conducting spray drying; and then, conducting high temperature solid-phase reaction to the 
reclaimed precursors by means of being subjected to the first stage of calcination and the second 
stage of calcination in sequence, and thus, the reclaimed cathode material of lithium-ion battery can 
be obtained. The reclaiming method of the present invention is at low cost, wherein, the raw 
materials utilized are free of acid and alkali, and without waste water discharge and exhaust gas 
emission, which is conducive to protecting the ecological environment, and thus the material 
consumption and cost can be reduced effectively. The present invention adopts simple process and 
has high recycling rate, as well as contributes to large-scale industrial production, and thus, it shows 
considerably broad application prospects.

Title: Combination marking-out tool
Inventor: EICHINGER HEINRICH
IPC: B43L7/12
Filed: 1980-02-29
Abstract: The handle (1) has two stop edges (18). A protractor (2) is fitted in place in the handle (1). The protractor (2) has scales for the angular degree graduation (13) and an additional millimetre scale (12). The latter starts from a bore (7) for a drawing-pencil insert. The bore (7) is provided in an angle (3) rotatably arranged about the axis (6). Thus the millimetre scale (12) can indicate the respective distance between a workpiece edge and the bore (7) for the drawing-pencil insert. The selected angular degree position or the millimetre distances can be locked on the protractor edge. The angle (3) can be turned through 90 DEG  at the protractor so that the half circumference can be divided into angular degrees. Together with an insert bore (7) for the drawing pencil in the angle (3), so-called pierce holes (10) in a scale (15), which can be precisely adjusted by displacement, at an edge of the angle serve to mark out parallel lines. <IMAGE>
